2 Peter 1:12-16

Wherefore I will not be negligent to put you always in remembrance of these things, though ye know them, and be established in the present truth. Yea, I think it meet, as long as I am in this tabernacle, to stir you up by putting you in remembrance; knowing that shortly I must put off this my tabernacle, even as our Lord Jesus Christ hath shewed me. Moreover I will endeavour that ye may be able after my decease to have these things always in remembrance. For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty.
